Root hair cells. Plants absorb water from the soil by osmosis. ... Root hair cells are adapted for taking up water and mineral ions by having a large surface area to increase the rate of absorption.
Answer:
F1) 1/4 = 25% de la porgenie será AB, IAIB
1/4 = 25% de la progenie será heterocigota para el tipo A, IAi
1/4 = 25% de la progenie será heterocigota para el gruo B, IBi
1/4 = 25% de la progenie será homocigota recesiva, ii
Explanation:
- El gen I determina el tipo de sangre de una persona. Es un gen dialelico que muestra alelo dominante I y recesivo I.
- En personas de tipo A, los alelos son IA dominante, i recesivo.
- En personas de tipo B, los alelos son IB dominante, i recesivo
- IA e IB son codomiantes entre si, lo que signofica que hay un tercer fenotypo IAIB, expresando ambos tipos de sangre juntos.
- El alelo i es recesivo siempre.
Genotipo A:
- IAIA, Homocigota dominante
- IAi, Heterocigota
- ii homocigota recesivo
Genotipo B:
- IBIB, Homocigota dominante
- IBi, Heterocigota
- ii homocigota recesivo
Genotipo AB:
- IAIB, Homocigota dominante

The answer is sliding filament.
Muscle fibers are made up of myosin and actin filaments that straddle one another in alternating sequence. The myosin has myosin heads that act on the actin and enable the myofibrils to slide across each other in opposite directions. This causes the muscle to shorten hence contract. This is an energy-requiring process (hence hydrolyses ATP) and also requires calcium ions. In an animation, the myosin would seem to ‘walk’ on the actin filament.
B) They maintain balance in the cell.
That mix of hydrophobic and hydrophilic, in other words, the mix of repelling and attraction maintains the aqueous balance in a cell and it's exterior.
